We present integrated-light spectra of 8 Young Massive Clusters (YMCs) in themetal-rich spiral galaxy NGC 5236 (M 83). The observations were taken with theX-Shooter spectrograph on the ESO Very Large Telescope. Through the use oftheoretical isochrones and synthetic integrated-light (IL) spectra we derivemetallicities and study the radial metallicity gradient observed through theseyoung populations. For the inner regions of the galaxy we observe a relativelyshallow metallicity gradient of $-$0.37 $\pm$0.29 dex R$_{25}^{-1}$, agreeingwith chemical evolution models with an absence of infall material and arelatively low mass loss due to winds in the inner parts of the disk. Weestimate a central metallicity of [$Z$] = $+$0.17 $\pm$ 0.12 dex, findingexcellent agreement with that obtained via other methods (e.g. blue supergiantsand J-band). We infer a metallicity of 12+log(O/H) = 8.75 $\pm$ 0.08 dex atR/R$_{25}$ = 0.4, which fits the stellar mass-metallicity relation (MZR)compilation of blue supergiants and IL studies.
